The invention relates to a method for calibrating a write head for producing a printing plate. The object of the invention is to indicate a method which permits an imaging system to be adjusted quickly, simply and without errors by using test exposures. In a method for calibrating a write head for producing a printing plate, in which, by using test patterns produced with the write head, the deviation of a property of the write head from a reference value is determined, and in which a corrective parameter in the write head is adjusted in order to compensate for the deviation, the invention consists in that test patterns that can be evaluated visually with regard to the writing quality are produced in a plurality of test fields (41, 49, 54) with different parameter values, an identifier (42, 50, 55) that can be picked up visually is produced with each test field (41, 49, 54), the identifier (42, 50, 55) of the test field (41, 49, 54) which appears best in terms of quality is entered into a control device (26) for the write head (16-19), and, in order to produce the printing plate (6) by using the entry of the identifier (42, 50, 55), the parameter value with which the test field (41, 49, 54) that appears best in terms of quality was produced is set automatically.
